.GLAzED STRUCTURE.

SPECIFICATION forming part of Letters Patent No; 690,121, dated December 31, 1901. Application 'filed October 29, 1900. Serial No. 34,829. (No model.)

T0 all wton t may concern,.-

Be it known that I, AARTHUR EDGCUMBE `RENDLE, a subject of the Queen of Great Britain, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Glazed Structures, of which the following is a specification.

My invention relates particularly to glazed structures of the kind shown in my Patent No. 488,663, of December 27, 185%2. lIn my prior patent I have shown a glazed structure comprising inclined troughs or astragals and cross-troughs constructed and arranged to connect and support `the panes of glass at their edges and to receive and carry off all the water accumulating upon'the panes or leaking through them at the joints. The troughs or astragals in the -glazed structure shown in my prior patent are arranged Vunder the `longitudinal joints ot' thel panes of glass, and over the joints are arranged caps, which are secured to horizontal bolts arranged across the astragals by means of verticallyarranged eyebolts. The cross-troughsrest trough is providedlmivith` a main gutter and a supplemental gutteli; The waterwhich finds its way into the small or" supplemental gutter passes into the main gutter through an opening in the bottom of the supplemental gutter. The cross-trough is provided `with supports for the adjacent edges of the glass. The supplemental gutter is straight on one side and inclined on the other; but the construction is such as to afford a very serviceable means for collecting water of condensation or water that leaks through the joints and carrying it off to the sides of the structure or to the astragals, which convey it to the edges of the structure. I have found in practice that itis desirable to connect the caps with the astragals by means of a yielding connection in order that the parts may not materially loosen when not used or when the nuts on the bolts slip. I have also found it desirable to provide means for preventing the lower edges of thecapsfrom slipping on the panes while the bolts arebeing tightened.

In my prior patented structure I showed no means for ventilation; but by my present im- 1n recesses in the astragals, .and each cross` Fig. l. `in crosssection or U-shaped, as" shown in Figs Band 4, or they may be of other snitprovements I provide for ventilation through the astragals and through the caps.

`The cross-troughs in the prior structure at one'side of the supplemental gutter are inclined; but it sometimes happens that the gutter becomes so long that the water tends to run over the 'inclined side of the gutter, and according to my present improvements I so alter this inclined side as to avoid this possibility.`

In the prior struct-ure it sometimes happened that moisture or water would creep along the under side of the cross-trough, and in order to avoid this I provide at each end of each section of the cross-trough a flange projecting downwardly, preferably into the inside of the astragals on which the crosstrough rests.

In the accompanying drawings, Figure 1 is a'view of a portion of a glass roof constructed `in accordance with my present invention.

Fig. 2 is a detail View in section, showing the manner of connecting the caps to the astragals and the `manner of arranging the crosstroughs. Fig. 3 shows a transverse section on` the line` 3 3 of Fig. 2. Fig. 4 shows a transverse section on the line 4 4 of Fig. 2. Fig. 5 is a perspective view showing more clearly the shape of the cross-trough and the manner `of arranging it.

The inclined troughs or astragals A are usually arranged equal distances apart and extendfrorn the bottointo the top of the inclined root', and the cross-troughs B, which are preferably made in sections, are arranged atright angles tothe troughs A, as shown in The ast ragals A may be rectangular able shape, and they support on the upper ends of their sides a the panes of glass C, which are symmetrically arranged side by sidein the same plane without overlapping edges. The longitudinal edges of the panes are separated, as indicated, and over the intervening space between thepanes are located metal caps E, which may be curved, but are preferably of the form shown. 'lhese caps are heldin place by vertical bolts D, which extend through the interval between the panes of glass C and are connected to curved ICO or U-'shaped strips of nietal F, which are secured to the astragals by means of cross-bolts G. A suitable number of bolts D are employed, located at suitable distances apartito securely hold the caps Ein place. The curved pieces of metal F form yielding connections between the astragals and the caps E. When the nuts of the bolts D are tightened, the

strips F are distended and exert a pressure on the caps, holding them tightly in place, and these curved strips provide such yielding connections that should any of thefpartsjof the structure change positions the caps will be made to automatically compensate for this change and at all times fit the structure tightly.

In the present instance the caps E have their lower edges e turned up to form a double thickness of metal; but this double thickness is comparatively narrow, and there is a tendency for the edges to slip on the glass when coming in direct contact therewith. In order to prevent this, I interpose between the lower edges of the caps and the glass C strips of lead H, which are preferably L-shaped in cross-section, as shown in-Fig. 3, one portion of the strip lying on the surface of the glass beneath the edges of the cap, while the other portion projects downward across the edge of the glass toward the troughs or astragals A. These strips of lead I-I are removable and are held in place only by the caps.

In order to provide for ventilation, openings a/ are formed in the sides of the astragals near their upper edges and also in the top of the caps, as indicated at b. Any water entering through the openings b will flow into the bottom of the astragals A, and there is no danger of leakage on thi-s account.

The troughs A may be supported on the frame of the roof in any desired way. In order to support the panes at their upper and lower edges and to convey off water which may leak in through the joints or accumulate by condensation on the panes,I employ cross-troughs B,which are preferably made in short sections and supported in recesses 0,2 in the trough or astragals A, as shown in Fig. 5. Each crosstrough is preferably made of sheet metal having a bottom g and sides g g2. The side g2 is slightlyshorter than the side g, so as to leave a small space between its upper edge and the glass to allow water of condensation to pass into the main gutter or channel of the trough. The side g is prolonged by being bent inwardly and downwardly parallel with the outer side of the trough to within a short distance of the bottom g. It is then bent inwardly and carried along parallel to the bottom g and then bent upwardly parallel with the lateral projection g5.

the side g, thus forming a supplemental trough or gutter y. 'The metal is then. bent laterally and folded upon itself to forni aledge g3. It is then bent upwardly and laterally to form a su pport for the adjacent edges of the panes. The upper panes rest on the ledge g3, the lower ones on the ledge g4 at the top of the side g. This pane is also arranged under A The construction is such as to form a small gutter y, having per forations Q7, through which the water which finds its way in at the joints passes into the main gutter or channelfrand thence into the astragal A. As before stated, the water of condensation passes from the under sides of the pane above the sides g2 of the trough into the gutter or channel m. It will-be observed by an inspection of the drawings that the cross-troughs are arranged to empty into the inclined troughs and that provision is niade for draining off all water that may tend to accumulate either on the upper or lower surfaces of the roof.

In my prior patent above referred to one of the walls of the supplemental troughs y was inclined, and there was a tendency sometimes for the accumulated water to flow out over the top or edge'g4; but by constructing this trough in the manner shown particularly in Fig. 2 this danger is avoided. In order to prevent water from creeping along the bottom of the troughs to too great an extent, the cross-troughs are formed with ianges J at their ends. Any water creeping along the bottom of the trough will be arrested by these flanges and diverted into the astragals.

I claim as my inventionl. The combination of a series of inclined troughs or astragals, provided with ventilating-openings, panes of glass supported on the upper edges of the sides of the troughs, caps arranged over the adjacent edges of the panes, and having Ventilating-openings and yielding connections between the caps and the astragals.

2. The combination of a series of inclined troughs or astragals, provided with ventilating-openings near the top of their sides, panes of glass supported on the upper edges of the 'sides of the troughs, caps arranged over the adjacent edges of the panes and having ventilating-openings in their upper portions, and means for securing the caps in place.

In testimony whereof I have hereunto subscribed my name.
